Sapphire Dual-X R9 280x, is this as good as they will get?
I'll try and give as much specs as I can to help if I can push these cards any more.
Windows 7 Ultimate 64bit
Asus p5b-f deluxe mb
3gigs of ram
Corsair CS750M 80plus gold 750 watt psu
2 Sapphire Dual-X R9 280x model 11221-00-20G
~705 KH/s is about the max I can get with both cards, I have tried many configs posted from different sites and this is my config
cgminer.exe --scrypt -o ltc.give-me-coins.com:3333 -u xxxx -p xxxx -g 2 -I 13,13 -w 256,256 --thread-concurrency 8192,8192
I've tried lowering the threads but nothing gets accepted and anything higher than 8192 cgminer crashes before it gets to do anything
This is about 5 mins into mining....
